IMPROVEMENT IN PEN'RACKS.

Specicationforming part of Letters Patent N0. 131,937, dated October 8, 1872,

To all whom it may concern.-

Be it known that I, EDWARD CLARKE, of Winchester, in the county of Litchfield and State of Connecticut, have invented an Improvement in Pen-Racks, and which is termed an Adjustable Pen-Rack, of which the following is a speciiicationr:

My invention consists of an improved penrack, in which the arms are adjustably attached to the end of a clamp-spring, so that they may be adjusted to their proper relative position when the clamp is applied to an inkstand, sand-boxes or other articles or xture of varying sizes, as hereafter described.

In the accompanying drawing, Figure lis a plan or top view of a pen-rack which embodies my invention, `the same being shown as attached to an ink-stand; and Fig. 2 is a side elevation of the same.

vA A designatearms of any pleasing design and provided with suitable notches a al a for the reception of a pen-stick, pencil, or like At the lower end of each arm A I form a short shaft, b, Fig. 2. B designates a sheet-metal spring of U-form and provided with a small coil, c, at each end. The shafts b b are forced into the coils c c, which spring open to receive them, and have sufficient elasticity to hold the shafts b b within said coils and still allow the arms to be turned to any desired position or angle to suit the1 article upon` which it is placed. The spring B is then sprung upon the sides of any ordinary inkstand, D, so as to clasp the same, and the arms A A are adjusted sidewise by swinging said arms upon `the hinge formed by the shaft b and coil c, so that their ends may be set the desired distance from each other when the vpen-rack is in position for use, as show n in the drawing.

If desired, the spring may be made in two or more parts overlapping each other and made to extend, by sliding endwise, something after the manner of spectacle-bows, by which arrangement the spring is adapted to inkstands, sand-boxes, or other article or fixture of larger range of sizes than it can be with a spring composed of a single piece.

By my invention I produce a light and cony venient pen-rack, which may readily and firmly be attached to ink-stands, 8vo., of varyin g sizes;

its arms may be adjusted so as to bring their upper ends at the same distance from each other, whether the clamp-spring B is thrown open more or less, by clamping diii'erent-sized `objects; its parts are detachable for conve- EDWARD CLARKE.
